测试环境：win2003

1.确认你的机器或服务器安装了SMTP服务器，如果没有安装请到添加删除程序里面的添加删除组件中添加电子邮件服务。

2.安装jmail4.3

3.找到jmail.dll（安装目录下）

4.执行Program Files/Microsoft Visual Studio .NET/FrameworkSDK/Bin/ildasm.exe（可使用Visual Studio .Net 2003 命令提示),

格式如下：tlbimp c:/Program Files/Dimac/w3JMail4/jmail.dll /out:myJmail.dll /namespace:myJmail

生成myJmail.dll后，copy到web的根目录的bin目录

5.代码
